Hello,
I am trying to implement basic data types transformation between UML2
class model and datatools SQLModel. My first option is make that by
means of matched rules but in this case no rule is executed.
This is an example:
rule test {
from
i : UML!DataType
to
.........
}
This rule is never triggered even though my model looks like this:
.........
<type xmi:type="uml:DataType"
href="BasicTypes.uml#_T2J54JEqEdy2scAHXnZ0kg"/>
.........
In the other hand if I make an explicit access to the property "type" of
element property I manage to retrieve data from his type correctly.
I am using ATL 2.0.0 with Eclipse Europa fall maintenance and I have
checked the "allow inter-model references" option in the configuration
launcher.
In spite of being able to solve this problem using called rules I rather
use matched rules.
Any idea?
Thanks
JC

Hello,
Did you add BasicTypes.uml to the source models of your transformation?
